A mixture of two hydrocarbons, ${\mathrm{C}}_8{\mathrm{H}}_{18}$ (octane) and ${\mathrm{C}}_7{\mathrm{H}}_8$ (toluene), has a mass of $163\mathrm{g}$. The hydrocarbon mixture is burned in excess oxygen to form a mixture of carbon dioxide and water that contains 1.32 times as many moles of carbon dioxide as water. Find the masses of ${\mathrm{C}}_8{\mathrm{H}}_{18}$ and ${\mathrm{C}}_7{\mathrm{H}}_8$ in the mixture. mass of bacerect g mass of ${\mathrm{C}}_7\mathrm{H}$
